Why, so it is! 

I remember hearing a Cessna take off and realizing it was the same sound as the flat four in my old bug.  The cruisemaster's cowling looked like it had a horizontally opposed engine, I was guessing.  It's such a good engine design! 

Caspian Sea Monster:
Modern light civil aviation is dominated by air-cooled flat boxer fours and sixes - so yeah, basically like a giant Beetle or 911 engine with dual spark.  The helicopter I learned in is (was :-() powered by a Lycoming O-360 flat four.  Radials are... not necessarily higher maintenance, but more difficult to work on due to the cylinder arrangement, and water-cooled engines were a fad that didn't really last much past WWII due to the weight and the serious oh-shit factor of springing a coolant leak.

Water-cooled I6s and V12s are just sexier though.   :-P

bhtooefr:
Although, as I understand, watercooled inline-4s are becoming more popular in Europe. (Specifically, two different aero conversions of the Mercedes-Benz OM 640 2.0 automotive diesel.)

so good in fact that the Porsche 959, as I learned watching an older episode of Top Gear last night, used a twin-turbo flat 6. it was also the fastest production road car ever made at the time.
